Medicine

Vascular dementia refers to a progressive decline in memory and cognitive functioning caused by a blockage or reduction in the blood flow to the brain. When the blood supply to the brain is interrupted, brain cells are deprived of vital oxygen and nutrients, causing damage to the cortex of the brain—the area associated with learning, memory, and language. Vascular dementia is the second most common type of dementia after Alzheimer's disease, accounting for up to 40 percent of dementia cases in older adults.
